Jinny,
First, I want to thank you for mentioning this forum in the Painter list. I doubt I would have found it otherwise. [img]/infopop/emoticons/icon_smile.gif[/img]
I noticed you mentioned your Wacom drivers as version 4.52. FWIW, there are newer drivers available. I have 4.55 on my system and for all I know those might not be the newest. As you seem to have gotten the brush working as it should it's unlikely that drivers on your system were the culprits in the aberrant behavior you were seeing.
